Dacar; if you must know.One was a 30-06 die,the sizer ,the bore that sized the neck was so rough(like the cutter tips were chipped,you being a machinist should know what that looks like)it could not resize the brass,every lube tried ,stand on the press handle,(sounds of brass about to seize).Dealer I bought them from,didn't believe me(probably just like you),used Lee lube,forced,siezure.Replaced with a different color,I had the 100 cases done in 15min,no prblems.
Number 2: Breech Lock press,needed just a cheaper backup single stage for forming ect... couldn't get things to come out concentric,tried,different dies ,same.took dies out and ran the ram up ,looked down the die hole,ram OFFCENTER approx, 1/16",Took back for full refund,ordered different color,works great for what I needed it for.
number 3: 9mm luger die set,this is the one that works,but threads were sharp and full of burrs(a person could easily slice a hand open,turned in press difficult),same with the seater ,sliced up the o-ring in short order,I put them all in the lathe and polished all threads smooth.now does work.

BTW I work in a Stainless shop ,Food grade everything is, we will not be working if we left things rough and not good quality. Things MUST be "pretty" our customers are happy for it.
